Abstract
The auxiliary management and control channel (AMCC) is an extra channel transmitting control and management signal to not change the GPON frame and reduce the PON system latency. In this paper, we demonstrate AMCC for control information transmission in a coherent frequency division multiplexing passive optical network (FDM-PON). In our work, we introduce the multiplication scheme of digital AMCC signal superimposition theoretically and show that the multiplication scheme can maintain a high signal-to-noise ratio (SNR) for the main signal. Thus, we apply the multiplication scheme for the AMCC signal superimposed to the coherent FDM-PON. In addition, we propose a novel extraction algorithm without interference cancellation to detect the AMCC signal. A 4-band coherent FDM-PON system with a total data rate of 100 Gbps and a 24 Mbps non-return-to-zero (NRZ) signal is demonstrated both through simulation and experiment.
